Are you forced to start over from a new device?

I upgraded my phone and I'm stuck back at level one all the achievements are there but i lose my progress?

I'm afraid of that. Is there any way to save the game progress? If the game needs internet for playing, you should save our status in your servers...

Save game progress on old phone with Titanium Backup on your SD card and download Titanium Backup on the new phone with the game also downloaded. Then you can pop your old SD card to your new phone (or whichever SD card you want to use that has the backup on it) and Restore Data.

There isn't a way for iPhones unless you jailbreak, I think, you can search for data backup on App Store. Most of the time be careful because it may only save the app name and not the data.
